Here’s my guess. Roberts, who has shown animus toward the Trump administration in some of his opinions will join the “liberals” — Breyer, Sotomayor, and Kagan — in decisions that favor Biden. Many commentators will simply ascribe Roberts’s rulings to his desire to maintain an appearance that the Court is non-political. They will also ascribe to him a desire to fend off court-packing by making it seem less threatening to Democrats, despite its supposed conservative majority. The mainstream media will simply ignore or minimized Roberts’s animus.
But Roberts plus the three lefties do not a majority make. So how will Roberts achieve his real objective, which is to remove Trump from office? He will appeal to Gorsuch, who seems to march to a different drummer than the Court’s real conservatives (Thomas, Alito, Kavanaugh, and Barrett). “Neil”, he’ll say, “here’s our chance to reassure the Democrats, who would surround us with their lackeys, that we aren’t rubber stamps for Republican policies.” And so Gorsuch will join Roberts and the lefties, for an anti-Trump majority. And perhaps (though I doubt it) Roberts will be able to recruit Kavanaugh or Barrett to the cause of making the Court seem to be above partisan politics. (Ironically, that’s precisely what Roberts will be engaged in, and everyone will know it.)
And so, Trump will lose despite evidence of massive election fraud in key Democrat-controlled States. And when the Democrats next get their hands on the Senate, court-packing will proceed apace, and Roberts will be an impotent chief justice who is dominated by the Court’s new, permanent left wing.
